Abstract

An analysis of LSTF Surge Line Break experiment (OECD/NEA ROSA-2 test 1) has been performed with TRACE code. This test, included within the OECD/NEA ROSA-2 project and performed in Large Scale Test Facility (LSTF), it is attempted to analyze the phenomenology and different accident management actions after the occurrence of a surge line (SL) break with failure of High Pressure Safety Injection (HPSI). The comparison between experimental data and the results obtained with TRACE code shows that, in general, the main phenomena are well reproduced.

Additionally, a broad analysis of Surge Line Medium Break Loss of Coolant Accident with HPSI failed in a Westinghouse PWR has been performed taking into account different accident management actions and conditions in order to check their suitability.

These works has been performed in the framework of OECD/NEA ROSA-2 and CAMP projects.
